Barcardi, A T2 on your QLS? Is the QLS running your whole system? If it is, the T2 may constrict because it is designed as a source power cord and not for high power applications. The best PC to place between the wall and a power conditioner in a full Tesla system is the Precision AC as you already have it. Put the T2 on your amp and T3 on the sub and then switch them just to make sure you like it.
